An NVCC student celebrates the end of their semester with a trip to King’s Dominion, where they choose to ride the Intimidator roller coaster. The first hill of the roller coaster is 93meters tall. If the cart goes over the top of the first hill at 3m/s and we assume there is no air resistance or friction… How fast is the cart going when it reaches the ground (assume the cart goes all the way to the ground. Yes, I have ridden this ride and I know it doesn’t actually do this. Just go with it.)? The cart then goes over another hill that is 25m above the ground. How fast is the cart moving at the top of this second hill? Explain why it wasn’t necessary to know the mass of the cart to do this problem.

You have a 4.7kg block of ice that is at -23 deg C. If you want to end up with 4.7kg of liquid water at 93 deg C, how much heat do you need to add to the ice? (Specific heat of liquid water = 4,186J/kg degC; Specific heat of Ice = 2090 J/kg degC; Latent heat of fusion for ice = 334,000J/kg)

A certain pendulum has a period of oscillation on earth of 2.4 sec. If it is taken to Planet X, it has a period of oscillation of 5.9sec. What is the acceleration due to gravity on the surface of Planet X? To what new length should the pendulum be extended to make its period of oscillation on Planet X be double?

A heat engine undergoes the following thermodynamic processes as it goes through it’s cycle: Step 1: Isovolumetric (isochoric) increase in pressure from Po to 5Po Step 2: Isobaric expansion from Vo to 4Vo Step 3: Isovolumetric (isochoric) decrease in pressure from 5Po to Po Step 4: Isobaric compression from 4Vo to Vo On your scratch sheet, draw the PV diagram for this cycle. What is the work done in one cycle of this engine in terms of the values given?

A 12m long bar made of copper starts at 21 deg C and is heated to 189 deg C. What is final length of the bar? The coefficient of linear expansion for copper is 17×10^-6/deg C.
